Price is residential revenue divided by residential kilowatt-hours sold, for bundled service only. Typical bill is that utility’s residential revenue spread over its residential accounts and twelve months, not a quoted tariff. The median priced utility charges 13.84¢ per kWh.

Price is only half of it

The median Idaho utility also leaves customers without power for 2.9 hours a year. A cheap utility that is out for two days a year is not obviously a bargain. See Idaho utilities ranked by outage time, or the utilities that charge the most and deliver the least.
